Casting sand or some other factory sludge in the cooling system. Killed my heater core and maybe more.

No heat! clogged heater core! grit and slime in dirty/discolored oem coolant (10 yr/150k mile rated). Never touched or added to, unless undocumented by dealer. This is our family vehicle that my wife/kids use daily, and it is about 10f here in vt right now. Very common Chrysler issue apparently and dealer does nothing but attempt to flush multiple times which does not solve the problem and is a huge inconvenience! I am still under 5 yr/100k powertrain warranty, since when is cooling system not part of power train? heat was reduced last winter, this winter virtually none. Dangerous to constantly clear the windshield with no defrost! this needs to be a recall.

Improper design of oil cooling unit - weak and incapable of repeated maintenance stresses. Scheduled oil change with local auto maintenance shop revealed significant amount of oil coating rear of engine, transmission bell housing, and light sheen of oil coating many components on the undercarriage. Pooled oil on the engine block at the front, directly underneath oil filter housing. Hours of internet research leads me to multiple Jeep message forums with similar/identical scenario. Every owner finds cause in faulty/compromised "adapter-engine oil filter" Jeep part number 68105583aa. Noted that this part has been upgraded/revised to an ae designation, thus revealing that Jeep knows this part to be faulty and/or of inadequate design. Vehicle was stationary (parked) when this happened, but only took note of a potential problem when I noticed an oil spot where I always park at my office, and at home. No vehicles I own have ever left an oil spot before this.

When changing the oil . When you remove the oil filter there is a plastic part on the shaft in the oil filter housing. This is a valve that controls the oil if the filter gets gummed up the presser causes this valve to open so that the oil will still flow if the filter is clogged. This plastic valve breaks during normal oil changes. To fix this 10 cent part you have to buy a whole new oil cooler unit at the cost of $237. 00 also to have the dealership fix it your looking at $800 plus for a 10 cent part. Jeep changed the oil cooling filter unit in the 2014 models. This also happens not only in the Jeep jk v6 but also in Dodge chargers and any v6 models that use this same filter oil cooler unit. Part # 05184294ae number on image: 1 category: 3. 6l gas; engine msrp$237. 00 price may vary by dealer adapter engine oil filter seems like a ripoff that you can not buy a 10 cent part but have to buy a $237 unit that is not needed.
The engine has released more than one gallon of antifreeze into the oiling system in less than 500 miles. After removal of the valve cover, a fracture in the cooling system cylinder head water jacket has been found between cylinders 3 and 4 that permits coolant to enter into the oiling system. The dealership stated that the cylinder heads are known to crack without cause, can be replaced with a cylinder head that maybe prone to cracking again and in additon will require several more components to be replaced. The dealership offered no further information.

2005 Jeep Wrangler. Well maintained. Highest quality oil, spark plugs, air filters, cooling system. Camshaft failure at roughly 50,000 miles. Excessive wear causing knocking. Diagnosis from Chrysler: new engine required. No overheating, no abuse. The oil pump drive assembly gears are worn down so oil is not flowing properly. This is a possible cause for the camshaft failure. The other possible cause for the camshaft failure is that it is a flat tappet camshaft from the factory. This specific type of camshaft needs the zddp oil additive. Modern oil does not contain zddp because it causes catalytic converter failure. Without zddp excessive wear occurs. This is covered in sae bulletin # 770087. Sae is the society of automotive engineers. Once wear reaches a certain level further wear is rapid and causes catastrophic engine failure. Furthermore, my Jeep is still under powertrain warranty. However, my warranty has been unlawfully denied because I have some unrelated aftermarket parts on my Jeep. Litigation is pending on this issue. Chrysler has gone against their own written warranty, and well as federal law (magnuson-moss warranty act).

The contact owns a 2010 Jeep Wrangler. Within six months of owning the vehicle, there was an excess build up of sand on the engine block which affected the cooling system. The vehicle was taken to two different dealers. The engine was flushed, but the failure continued. The vehicle was to be taken back to a dealer for further diagnostic testing. The manufacturer was notified. The VIN and failure mileage were not available.

My 2006 Jeep Wrangler has been a problem since I bought it. The vehicle has been back to the dealership for part replacement repair over 7 times, and it has only 24,000 k. Won't detail each mechanical issue, but I have been very disappointed in this vehicle, and got rid of it last week.

We purchased a 2001 Jeep Wrangler about two years ago. Back in November, the vehicle began to overheat. Thinking it was the hoses or radiator cap, we replaced both, which stopped it for awhile. In December, it began to leak again, so we replaced the radiator. It is now January and it has begun to leak again. We have ordered a new radiator, but it doesn't appear that the leak is coming from the radiator, and after reading some of the complaints on the internet regarding the 2001 Wrangler, we are afraid it may be a cylinder head. Has there been a recall on this? there seems to be a lot of complaints related to it.

I currently own a 2007 Jeep Wrangler . I have experienced a stalling problem with vehicle 5 time in the last 2 months. 4 of the 5 time I was traveling at night at speeds of 50 to 65 mph on an interstate. The reason I am writing this complaint is I almost rear ended a tractor trailer running at a slower speed after the stall turned of the light and gave me no brake power. This is very dangerous almost costing me my life. I am taking it to the dealer to have a recall notice done on 03/21/08. This problem seems to be coming quite common on these Jeeps, I hope a death does not happen before they fix the defect.

At approximately 3,000 miles vehicle stalled while driving up a hill at 45 mph. Radio turned off, lost control of steering, all lights lit up on dashboard. This lasted for approximately 4-5 seconds. Scary! took vehicle to dealer for flash"of computer per technical service bulletin (TSB). All was well until yesterday at 9,100 miles. Same exact thing happened! will have dealer check obd for error codes. This was a major safety problem and concern, could have been traveling at a high rate of speed on interstate with semi behind me. Then what? thank you for your time and assistance with this safety issue and potential for injury or loss of life. Just wanted the problem acknowledged and corrected.
1998 Jeep Wrangler exhaust manifold cracked. Contacted dealer to check about recall info after repair shop said this was common in 1997 and 1998 Wranglers. No such luck. Had it welded at my expense and have since spoken to many other folks having the same problem. Should be investigated.

Air-conditioning compressor failure air-conditioning evaporator coil failure air-conditioning refrigerant leaks and odors.
Persistent leak problems since Jeep was 6 months old. Return to dealer over 5 times before noticeable leaks stopped (behind dash board, floor at drivers and a passenger side) fix under originally warranty. 4 new leaks and return of two old leaks - not covered by extended warranty now dealer wants $650 to fix. Additionally have numerous transmission problems and paint rusting problems since a month after I purchase the vehicle.
Freeze plug cracked on perfect day of 70 degrees. Engine coolant lost. This happened in a parking lot - 02 mph in reverse. :) if it had happened on the freeway, permenent engine damage could have occurred due to overheating and leading to seizing.

Consumer states radiator and water pump failed.
See attached letter to daimerchrysler - will be sent via mail. No safety defect listed.
All three failures have taken place in the last three months. The latest being the catalytic converter. Have there been other failures reported.
My radiator has rotted out, including part of the core,this has never happened with any vehicle I've ever owned, I've lived and driven in the same conditions for my whole life.
The vehicle has developed an odor associated with leaking anitfreeze. 3 different trips to make repairs, no action on first trip, second trip, dealer replaced thermostat housing, third trip, dealer replaced radiator. Vehicle still has odor at different times. Seat belts have been replaced 3 times on right hand side and once on left hand side due to belts getting pinched in hardtop doors and damaging belts. Belt on right hand has had failure of seat belt inertia lock during hard stop. Electrical system: airbag light illuminated at various times, and at the same time the speedometer and tachometer failed momentarily. Fix was to clean and grease connectors. System is starting to repeat same problem, and dealer cannot find a problem. Steering column lower bushing has developed noise, after rain or onset of cold weather. Dealer states fix is to lube bushing, but problem persists after 4 dealer visits. Rear axle seals on left hand and right hand were leaking, resulting in rear wheel lockup with moderate brake application on damp pavement or sandy road surfaces. Dealer replaced both seals, but nothing was said about possible brake lining contamination or cleaning. Vehicle has had repeated water leakage from around windshield on left and right hand sides, right hand hardtop door hinge attach bolts, thru seals on cowl and around doors. Dealer has replaced all seals, rtv'd gaps, and installed updated door seals, but vehicle still leaks. Also, carpets were water damaged in front passenger area due to water leakage from vehicle body and airconditioning system. Vehicle has been kept for up to two days on two different occasions for water leaks and multiple repair complaints.
Water pump failed. Mjs.
Engine cooling system overheating, oil sensor gauge drops to zero, causing checking engine light to come on, in for repair 4 times.
